pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)

pg_fetch_assoc() returns an associative array that
corresponds to the fetched row (records).

pg_fetch_assoc() is equivalent to calling
pg_fetch_array() with PGSQL_ASSOC as the
optional third parameter. It only returns an associative array.
If you need the numeric indices, use
pg_fetch_row().

Note: This function sets NULL fields to
PHP NULL value.

pg_fetch_assoc() is NOT significantly
slower than using pg_fetch_row(), and
is significantly easier to use.

Note:
row became optional in PHP 4.1.0.

PostgreSQL query result resource, returned by pg_query(),
pg_query_params() or pg_execute()
(among others).

Row number in result to fetch. Rows are numbered from 0 upwards. If omitted,
next row is fetched.

An array indexed associatively (by field name).
Each value in the array is represented as a
string. Database NULL
values are returned as NULL.

FALSE is returned if row exceeds the number
of rows in the set, there are no more rows, or on any other error.

Example 1. pg_fetch_assoc() example

$conn = pg_connect("dbname=publisher");
if (!$conn) {
  echo "An error occured.\n";

if (!$result) {
  echo "An error occured.\n";
  exit;
}
 
while ($row = pg_fetch_assoc($result)) {
  echo $row['id'];
  echo $row['author'];
  echo $row['email'];
}
